Big Idea : Observation and description of changes in the world around us are the first steps in finding and learning about patterns A. Make a graph of your jumping jack data.

B. What does your graph show about jumping jack rate as time passes? (another way to say this is, what does your graph show about the relationship between the number of jumping jacks and time?)
The graph shows that the number of jumping jacks slowed down in time, which means the person is getting tired.
F.U. :
Is the relationship you found between the number of jumping jacks and time easier to see in the table or the graph? Explain your answers :
It is easier to see in the graph than the table, because it is easier to see the pattern of the data.
Strategy discussed in class :
1. Make sure that you leave some space at the top of the last dot, to make the graph neat.
2. Add the title and the 2 variables on the graph.
3. Draw lines between the dots to see the graph more easily.
Method to make a graph :
1. Select two variables.
2. Select an axis to represent each variable.
3. Select a scale for each axis.
4. Plot the data points.
